What is the domain and range of  y= -2x+3?

Mar 9, 2016

Domain: negative infinity to positive infinity
Range: negative infinity to positive infinity

Explanation:

Here there is no limit to the domain as there are no restrictions. The x value can be any number.
The output value (range), is also infinite since the input (domain) is infinite.

graph{-2x+3 [-10, 10, -5, 5]}

The line on the graph can extend to any value since there are no restrictions on the input x-value.
